CONTAINER APPLICATORr To all whom it may con-cm:

Be it known that I, RICHARD Snnn, a citizen of the United States, residingat Swiftwater, in the county of Monroe and State of Pennsylvania, have invented .certain new and useful Improvements in Containerv Applicators, of which the following is a specification t This invention. relates to container-applicators and has for .an object to provide a device of the class embodying new andimproved featuresboth as a containerand as an applicator. A further'objeot. of .the inventionis'to provide a containerhaving a plunger, or followerv moving therein to ex,

' pel the contents, with improved means for actuating the plunger.

A further object of the invention is to provide a container having a plunger, or follower, of improved type movable therein, .with a manually rotatable screw for feeding the plunger. I

A-further object of the invention is to provide/improved means for connectingthe plunger-operating screw with the container.

A further object ofthe invention is to provide a new and improvedtype-of applicator with improved {means for attachmg the same to the container.

:With these and otherobjects in view, the invention comprises the novel. units, elements, parts, combinations, mechanical movements and functions disclosed in the drawings,together with equivalents thereof,

as hereinafter more fully described and claimed.

vided withaa bead 13 forming an inclined annular SllOllldGIfll within the neck open- .lll .p r eferably be' composed of glass and has This container in most "cases will been shown section-lined to "indicate glass at Fig. 2,'butit is to be understood that such preferred material, or such section lining indicatingv suchmaterlal is no llmltatldn upon the present invention and the con-- tainer maybe made of any desired or approved material.

. To operate 'inconjunction with the container .a screw--15 is employed, preferably originally constructed as --a straight 'rod cross-sawed at 16 as indicated in Fig. "3. A

knurled head 17 is rigidly secured to the screw 15 after the plunger has been applied thereto. The plunger comprises a" nut 18 having piercing points 19 inserted into the -washer20 forming a part: of the plunger.

The washer 20; will preferably be composed vof cork; although the invention, isnot limited to such jm'aterial. The axial opening 21 through the washer 20' will be of .greater diameter than the screw 15 so that when applied to the nut 18 will 'be free from engagement with, the screw 15 as shown more particularly at Fig. 2.

The screw 15 with the knurled head 17' andplunger, will be inserted into the container 10 with the sawed. extremity disposed withintheannular-- tapered shoulder 14. The extremity is now expanded, by'insertiing an instrument into the saw kerfs, so that the expanded extremities will engage against, the. inclined shoulder '14 as indicatedat 22 n1 Fig."2,for-the head will be first expanded and the screw 15 inserted before the knurled head is applied, the screw being held against rotation within the-cone tainer by any convenient tooland the nurled head 17 applied thereto. V Thecontainerlt) .will be filled with the material as indicated at Fig. 2. E The filling may be accomplished either before the plunger 20 is inserted or after the plunger is inserted and filled through the saw kerfs 16 in the expanded extremity of the screw 15. The manner and time of filling will depend upon the nature of the materialfilled into the container.

After the container is filled, a washer 23 will be applied to the end. of the neck 11 and preferably secured thereon by some adhesive material, impervious to and insoluble in, the contents of the container. 'This washer 22 is preferably composed of cork and is of reduced thickness centrally as indicated at 24 in Fig. 2. The application of this washer to the container by the impervious adhesive will completely close the container against evaporation or discharge of the contents.

An applicator is now applied to'the structure', such applicator being shown as an entirety at 25. It comprises" a cylindrical portion 26 properly proportioned to embrace the bead 13 of the neck and a tapered portion 27 having a discharge orifice 28. For the purpose of proper sealing, the cylindrical part is preferably coated with the said impervious adhesive and applied to cover the washer 23 and the bead 13, and the marginal edge 29 is burnished down to engage against the underside of the bead 13 as indicated more particularly at Figures 1 and 2. If the contents of the container is liquid and volatile, a fibrous packing 30 will preferably be enclosed within the applicator as indicated at Fig. 2. A closure cap 31 is provided to close the discharge orifice 28 when not required for use.

"With the parts assembled and filled, as indicated at- Fig. 2, the contents are made available by inserting an instrument, such as a needle or pin, through the orifice 28 passing through the fibrous packing 30, if therein contained, and piercing the reduced portion 24 of the washer 23; Manual rotation'of the screw 15 by power applied to the knurled head 17 will cause the plunger to move along within the cylinder to expel the contents through the puncture of the washer 23 to saturate the fibrous packing 80 and be extended through. the orifice 28.

It has been found from experiment that, with the washer 20 of the plunger inen gagement with the interior of the cylinder but out of engagement with the screw, while the nut 18 is in engagement with the screw but out of engagement with the container, the turning of the screw will not materially rotate the plunger but will move it substantially only longitudinally to expel the contents.

It is obvious that the fibrous packing will be desirable only when the contents is liquid and when the contents is plastic or semiliquid can and will be omitted' It is also obvious that it the container is employed for a material suliiciently plastic the washer 28 may also be omitted, depending upon the cap 31 for suflicient closure of the container.

In any event, after the extrusion of the material from the orifice 28 and the applica tion thereof by the tapered applicator 27 or otherwise as may be found advantageous, the cap 31 will be replaced to close the orilice 28 and protect the applicator.

The present invention is intended for a container and applicator for highly volatile liquid medicinal preparations and, in its entirety in organized form, is capable of serving such purpose. It is, however,.not limited thereby or thereto.
